It is possible to set the options for ports in /etc/make.conf.  That is
how I handle it would poudriere which looks for make.conf files in
/usr/local/etc/poudriere.d and can use make.conf files that are specific
to each jail, ports tree and ports set (poudriere -z option to specify
the latter).

Specifying the options in make.conf also makes it easier to set options
globally for all all of the ports that you build so they are consistent.
For instance I specify these options globally:

OPTIONS_SET=CUPS APPLET OPENBLAS OBLAS SZIP LETTER GUILE2 GSSAPI_NONE KRB_NONE
OPTIONS_UNSET=GUILE1 NETLIB REFERENCE GSSAPI_BASE KRB_BASE KERBEROS

Port-specific options can be set like this:

graphics_gimp-help_SET=EN
graphics_gimp-help_UNSET=ALL

Back when I still used portupgrade, I found that dialog4ports got to be
really frustrating.
